Amalensi okukhanya angu-1.56 anombala oluhlaza okwesibhakabhaka oqoshiwe othambile

Amalensi okukhanya anombala oluhlaza okwesibhakabhaka angu-1.56 aqediwe kancane Isithombe Esifakiwe

Incazelo emfushane:

Izibuko eziningi zineziteshi ezimfushane neziteshi ezinde. Ukukhetha isiteshi kubalulekile. Ngokuvamile, siqala ngokucabangela ukukhetha isiteshi esifushane, ngoba isiteshi esifushane sizoba nensimu enkulu yokubuka, okuhambisana nendlela yokuphila yabantu abavame ukubheka omakhalekhukhwini babo. Umehluko phakathi kwamehlo mkhulu kakhulu, amehlo abantu abakwazi ukujikeleza kahle, nawo afanele iziteshi ezimfushane. Uma umthengi egqoke i-multi-focus okokuqala, enesidingo sebanga eliphakathi, kanti i-Add iphakeme kakhulu, khona-ke isiteshi eside singacatshangelwa.

Imininingwane Yokukhiqiza

Kumalensi aqhubekayo, uma i-Add inkulu, i-astigmatism iyanda (ikakhulukazi ukuhlakazeka okuqondile), futhi indawo ye-astigmatism iqine. Ngakho-ke, kufanele sizame ukunciphisa i-Add. Ngokuvamile, i-Add engaphansi kwe-+1.50 ine-astigmatism encane, ibanga elincane kanye nenduduzo ephezulu, kanti abagqokile abaneminyaka engaba ngu-50 ubudala banesikhathi esifushane sokuzivumelanisa nezimo. Uma i-Add iphakeme kune-+2.00, umgqoki udinga isikhathi sokuzivumelanisa nezimo.

Isingeniso Sokukhiqiza

Umklamo oqhubekayo wangaphandle: inqubo yokushintsha izinga eliqhubekayo yenziwa ebusweni obungaphambili belensi. Ukuzwela kokungafani kuphansi, futhi kusebenza kangcono kubantu abane-backrotation embi. I-High Add noma i-short channel esebenzisa umphumela oqhubekayo wangaphandle ingcono, kodwa insimu yokubuka incane.

Umklamo oqhubekayo wangaphakathi: I-gradient yenziwa ebusweni bangaphakathi belensi. Isifunda se-astigmatic sincane kakhulu, siphansi. Engeza noma isiteshi eside sifaneleka kakhulu kulo mklamo. Ungacabanga ngelensi njengefasitela. Uma usondela efasiteleni, insimu yokubuka inkulu.
